CUSPIDOR.

Specification of Letters Patent.

Patented June 17,1913.

Application filed April 20, 1912. Serial No. 692,060.

T 0 all 107mm 52- may concern:

lie it known that I, -WnvsLow A. Bowen, a citizen of the United States,residing at- Poughkeepsie, in the county of Dutchess and cuspidor. Fig.2 is a vertical section therethrough.

The cuspidor is preferably constructed as an integral member andprovided with inner walls 1, outer walls 2, a bottom 3 and a base it.The inner walls 1 form the bowl of the cuspidor and as illustrated thesaid bowl is of a decreased diameter downwardly. The small end of thebowl has its walls merged into the upper end of a discharge connection5, and as shown said connection is extended below the'plane of the loweredges of the walls 1 where it is adapted'to be extended through theopening 6 in a floor or any other suitable support 7.

c The walls of the bowl 1 are spaced from the outer walls 2 of thecuspidor and they are both connected "with the bottom 3 whereby theydefine therewith a. water circulating chamber 8. The outer walls 2 areof concave-convex form with their concaved surfaces disposed in opposingrelation with the walls 1.

Incident to the inclination of the walls 1 with the walls 2 and thebottom 3 it is evident that the chamber 8 is of an upwardly restricteddiameter so that its restricted portion is immediately in line with theflushing perforations 9 in the upper portion of the walls 1. Byrestricting the upper portion of the chamber 8 the water is crowded atthis point and it is compelled to enter the bowl 1 with greater forcethan were the chamber 8 of the same widthor diameter throughout. A watersupply pipe '10 may be led through the floor 7 and connected as at 11with the bottom 3 whereby water will be conveyed to the chamber 8. Avalve 12 in the pipe 10 has its stem 13 extended through the base 2 andexteriorly of the base the stem is provided with a manipulating wheel14;.

Now that the details of construction of the device are clearly describedit is evident that water rising in the chamber 8 will be dischargedtherefrom in small jets, the jets being extended down against the innersurfaces of the bowl 1 so that the latter will be constantly flushed aslong as water is permitted to discharge into the chamber. Theperforations 9 are preferably inclined downwardly and inwardly so thatthe water will be discharged with considerable force against the innersurfaces of the bowl.

The cuspidor described is extremely simple in construction, inexpensiveto manu facture and the arrangement of the flushing means thereforemaintains a perfect sanitary condition of the bowl at all times and whenthe device is used in such public places as hospitals, theaters orrestaurants or the like the spread of diseases will be. reduced to aminimum.

The bottom of the pipe 5 is exteriorly threaded as at 15 for attachmentto a suitable wastc conduit, not shown.

I claim A cuspidor comprising an integral member having an inner walldecreasing in diameter downwardly, and outer walls, and a straightbottom wall, the bottom wall being connected with the said inner andouter walls and said inner and outer walls being connected with eachother at their upper ends. and relatively arranged so as to definetherebetween a chamber of an upwardly decreased width and terminating ata point slight above a series of perforations formed in the inner walls,and perforations opening into the chamber at the restricted portionthereof, a water supply pipe entering the chamber through the bottomWall thereof, a base curved downwardly from the bottom, a valve in thepipe having its stem portion extended through the base and provided witha manipulator.

Tn iesiimony whereof I alhx my signature in presence of fiwo Witnesses.
